No check engine light and your reader says a crank sensor not learn? Either the led indicator died or your reader is displaying false info. Turning on ignition powers up all electronics and turns on all indicators in the instrument panel (lamp test at every ign on cycle). Specific leds are designated for more reliability than incandescent lamps with filaments to burn out. Oil, battery, check engine, seat belt, security, etc, are usually leds that last the life of most vehicles. I would be suspicious of false info when the cel isn't turned on as this tells an owner that an error occurred in emissions. The wrench indicator (another led) stores errors in memory related to chassis, body and network codes and only decoded by either aftermarket low cost scantools, high end scantools used in repair shops or GMs scantool. Generic readers cannot read wrench codes.

If you cannot perform suggestions given to continue diagnosing and troubleshooting at home, your options are to either find a repair shop with expertise in diagnostics or GM dealer.
